1983 Honda CB550SC · Engine Buying guide

Start with the repair area and the named contents

The Athena set and fibre valve-cover gasket serve different purchase scopes. Drain plugs, the crush washer and filter spring are separate items, while the genuine Honda pressure switch has its own replacement references.

Plan the gasket purchase before adding hardware

For cover work, the fibre gasket has named Honda references and a clearly stated single-gasket package. The Athena overhaul set is broader in description, but its individual contents are not listed. Check what your work requires before adding separate gaskets to an overhaul-set order.

Identify small oil parts by their job

The 12 × 18 × 1mm drain crush washer is a different purchase from the filter-housing spring. The spring references 15415-300-000; the genuine pressure switch has its own Honda cross-references. Match the original component and location rather than treating these small parts as interchangeable accessories.

Engine questions

Can I choose a full gasket package from its photograph?

The Athena product explicitly lists the 1983 CB550SC, but its written description does not itemize the package. Use the photograph to identify the product, then confirm any specific gasket or seal you need before ordering.

Which thread do the magnetic drain plugs list?

Both magnetic drain plugs list M12 × 1.5 and reference 92800-12000. Compare that specification with the fitted drain and its sealing washer; a shared reference does not establish the number of drain points on your motorcycle.

Is the filter-housing spring a replacement filter?

No. It is a separate housing component replacing 15415-300-000, with the 1983 CB550SC explicitly included in its application. The spring purchase does not include the filter element or turn the separate listings into a service kit.
